Abstract (en)
An SCR system (12) for use with an IC engine (10) includes a reduction agent doser (24) and a catalytic reactor (26). The reduction agent doser (24) includes a tubular housing (28) with an inside diameter. A target plate (32) is positioned crosswise in the housing (28) and terminates at a distance from the inside diameter of the housing (28). The target plate (32) directs a flow of exhaust gas in a radially outward direction. A baffle (34) is positioned crosswise in the housing (28) downstream from the target plate (32). The baffle (34) terminates at the inside diameter of the housing (28) and includes a center opening (40) for directing a flow of exhaust gas in a radially inward direction. A diffuser plate (36) is located downstream from the baffle (34). The diffuser plate (36) terminates at the inside diameter of the housing (28). A catalytic reactor (26) is directly coupled with a downstream side of the reduction agent doser (24).
